Unlicensed radio stations in 1933 tested the Radio Act of 1927 as to whether or not the Federal Radio Commission (FRC) had the right to regulate radio stations whose signals were allegedly intrastate. The FRC believed it could regulate such radio stations and proceeded to confiscate equipment, charge individuals with violation of the law, and bring them to trial, either in an injunction hearing, a criminal trial, or both. The most formidable case was that of United States v. Gregg et al. The challenge was met by the FRC and the judge, whose decision is still quoted in legal documents. The decision upheld the Radio Act of 1927 and the FRC's right to regulate all radio stations, licensed or unlicensed.
